ATTACHJIIENT FOR NAILING-MACHINES.

To all whom 'it may concern:

Be it known that I, Percy L. BILLINGSLEY, a citizen of the UnitedStates, residing at 1 Oak, in the county of Marion and State of Florida,have invented certain new and useful Improvements in Attachments forNailing-Machines; and I do hereby declarefthe following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the artto which it appertains to make and use thesame.

My invention relates to attachments for nailing machines and my objectis to provide means for automatically feeding the parts to be nailed,below the nailing head.

A further object is-to provide means for supporting the objects to benailed in position on the feeding device and a still f1. rther object is.to provide means for adjusting the several parts of the device, wherebyobjects of various sizes may be placed on the feeding device.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims.

In the accompanying drawings which are made a part of this application,Figure 1 is a side elevation of my improved feeding device in itsoperative position. Fig. 2 is an end elevation thereof. Fig. '3 is aview as seen on line 3-3, Fig. 1. Fig. 4 is a bottom plan view of afeeding plunger, showing the supporting frame therefor. Fig. 5 is anedge elevation of one section of the feeding 6 is an elevation of thelower end of one section of the magazineemployed in holding the articleson the feeding device. Fig. 7 is-a similar view of the opposite sidethereof. Fig. 8 is a bottom plan view thereof. Fig. 9 is a sideelevation of an arm employed for automatically operating the nailingdevice, and, Fig. 10 is an edge view thereof.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 and 2 indicatestandards which are employed for forming the frame of my improvedfeeding device, said standards being secured together in any preferredmanner, as by means of beams 3 and 4, said beams being extendedtransversely between the standards 1 and 2. Preferably. formed integralwith the upper ends of the standards 1 and 2 are plates 5 l and 6,respectively, said plates extending 1n-- channels 32, at

ards to form a bed plate and are reinforced on their lower faces bymeans of webs 7 Mounted upon the plates 5 and 6, are guide rails 8 and9, respectively, provided with a plurality of ears 10 and 11,respectively, through which extend clamping bolts 12 and 13,respectively, the ears 10 being provided with slots 14, so that theguide rail 8 may be adjusted towards or from the rail 9 to accommodateobjects of various sizes. The upper faces of the guide rails 8 and 9.are provided with grooves 15, and 16, respectively, in which are adaptedto extend tongues 17 and 18 of magazine forming sections 19 and 20, saidsections being preferably formed of angle iron and mounted on baseplates 21 and 22, respectively, to which the tongues 17 and 18 are fixedand in order to adjustably secure the magazine forming sections to therails 8 and 9, bolts 23 and 2t are introduced, respectively, through thebase plates 21 and guide rail 8 and the plates 22 and rail 9. Themagazine sections 19 and 20 extend vertically from the base plates 21and 22 and'in order to reinforce the sections 19 and 20, brace members25 and 26 are formed integral with the base plates and magazine sectionsand extend upwardly on the magazine sections a sufficient distance tothoroughly brace said magazine sections and two of the brace members areprovided for each magazine section and extend at right angles to eachother, thereby thoroughly bracing the magazine sections in bothdirections.

This device is adapted more particularly for feeding box ends below anailing ma chine, said box ends consisting of a frame 27, to which issecured a strip of veneer or the like 28, said frame and veneer, whensecured together, forming such as is employed for shipping fruits and byproviding the magazine, a large number of the frames and strips ofveneer may be placed in position to be fed below a suitable nailinghead, (not shown), automatically and to accomplish this result, aplunger is reoiprocatingly mounted below the magazine, said plungerbeing preferably formed in two sections 29 and 30, respectively, whichsections are secured together by means of a connecting plate 31. Theplunger sections 29 and 30 are adapted to travel on the plates 5 and 6,respectively, while the inner edges of the guide rails 8 and 9 areprovided with their lower edges, in which extend tongues 33 on themeeting edges of which rails are the end of a box sections will beprevented.

with a plum lty 35, which extend through connecting plate 31 and byconnecting plate is adjustably secured to the I means of stud bolts tothe plunger through the medium 0 suspended above the plunger section 29,while the opposite edge of the plate 31 is fixed to the section 30 by36. The forward edges of the plunger sections 29 aiid 30 are providedwith feeding lates 37, one edge of which extends beyond the ends of thesections 29 and 30 of said projecting edges are beveled on their lowerfaces to cause the feeding plates to positively engage the section ofveneerplaced above its respective frame 27 and cause the veneer to movewith the frame.

In operating the plunger to cause the same to travel below th oftheframes and tion to be nailed to e magazine and move one gether, power isapplied a lever 38, one end of which is 'pivotally secured betweenbrackets 39, at the lower ends of the standards 1 and 2,- while theupper end of said lever is pivotally-secured to an car 40, dependingfrom the central portion of the connecting plate 31, through the mediumof a pitman 41, said pitman being adjustable longitudinally, to adjustthe position of the plunger. The lever 38 is rocked in its bearing bymeans of an eccentric 42, carried by a drivin' shaft 43, saideccentricbeing secured to the ever 38 at a point between 1ts lower endand longitudinal center by means of an adjustable eccentric rod 44, andby this construction it will be readil seen that as the driving shaft 43is rotate the lever 38 will be swung back and forth, which will move theplunger below the magazine and automatically feed the frames, tained'therein, to the nailing device, the frame and veneer moving onto aplatform 45 of the nailing machine, said platform eing secured in anypreferred manner to one end of the plates 5 and 6 and in saline menttherewith.

The veneer is secured"- to the frame by placing nails through the veneerand into the frame and to complete'the nailing at one stroke, a head,carrying the requisite number of nails to'secure the veneer in position,is frame and the veneer an lowered into engagement therewith, the forceof the head being sufiicient to drive the nails into the veneer andframe, but, as the nailing machine forms no part of my invention, I deemit unnecessary to show more of the nailing machine than is re uired todemonstrate the full operation o my imare adapted to receive simi- 7bearing sectionof veneer in posit and veneer conthereby rocking with theaction proved feeding device and, with this end in provided means forautomatic-, ally operating the nailin view, I have g machine, so thatthe veneer will be secured to the frame, as soon as the same has beendeposited on the platform, which consists of a bar 46, mounted adjacentits upper and lower ends in bearings 47, carried y the beams 3,said barbeing vertically disposed and bifurcated at its upper end to receive aroller 48, that portion of the bar extending through the upper 47 beingpreferably square, so that the bar will be prevented from rotating inits bearings, at the same time allowing the bar to freely movelongitudinally through the bearings.

A bracket 49 is adjustably secured to the w bar 47, adjacent its lowerend, said bracket being adapted to engage the free end of a rockinglever 50, which is in turn secured in any preferred manner to thenailing head, so that when the rocking lever 50- is depressed, thenailing head will be likewise lowered into engagement with the frame andveneer thereon and in order to operate the rocking lever, co-incidenttodepositing the frame andveneer on the platform 45, an arm 51 is securedto the plunger sections 29 andi30 and depends therefrom, to the lowerend of which is adjustably secured a head 52, which is adapted to engagethe roller 48 and depress the lever'50, through the medium of the bar 46and bracket 49, the engaging end 53 of the head 52 being disposedsubstantially at an angle of 45 from the horizontal. The arm 51 and head52 are vslightly curved and are secured together by means of a bolt 54,carried by the'head 52 and extended in the arm 51, thereby allowingthehead 52 to be readily adjusted on the arm 51, to give a longer orshorter stroke to the bar'46 and it will be readily ger moves forwardlyto deliver the frame andveneer onto the platform 45, the in-. clinedportion of the head 52 will enga e the roller 49 and cause the bar 46 todescen the lever 50 and o crating the nailing head. As soon as the preturned to its initial position, the bar 46 is elevated to its initialposition by 'meansof a spring 56, which is interposed. between the acollar 57 on the bar lower bearing 47 and 46, the tension of the spring56, together of the rocking lever 50 on the bracket 49, being suficientto readily elevate the bar 46, extreme lower end of the rod 46 engagesthe lower edge of the lower bearing 47, thereby limiting the bar. Whenthe magazines are filled with the frames and veneer, the lowermost framewill rest in the magazine sections are elevated to such an extent thatsubstantially one-half the thickunger is 3 until the collar 58 on thethe upward movement of through an elongated 'slot 55 seen that asthe'plunpath of the plunger and the ness of the second frame is belowthe lower ends of the magazinesections, so that when the plungersections move below the magazine, those frames above the frame restingon the plates-5 and '6, will be held in their elevated position untilthe plunger is returned to its initial position, when all of theframesand veneerwill descend until the next succeeding frame rests uponthe plates 5 and 6, the parts of the nailing device and the feeder beingso timed that the veneer will be nailed to the frame by the time-theplunger reaches its initial position and'ready to deliver another frame.

- It will thus be seen that 1 have provided a very cheap and economicalmeans for automatically feeding-the parts of a box head in positionto benailed together and it will further be seen that the operation of thefeeding device may be ignpl'oyed to operate the nailing machine, so thatthe two devices will operate in conjunction and it will further be seenthat by employing the automatic means of feeding the parts to be nailedtogether, the output of the nailing machine may be greatly increased andthe box produced at a greatly reduced cost and, still further, it willbeseen that the several parts of the feeding to accommodate frames ofvarious sizes.

"What I claim is:

In a feeding device, the combination of plates and guide rails on saidplates adjustable one with relation to the other, said guide railshaving their, upper surfaces device may be adjusted grooved, of atwo-section laterally adjustable plunger adapted to reciprocate betweensaid guides; and a hopper arranged between the guide' rails forcontaining box ends and discharging the box ends in the path. of travelof the plunger, said. hopper having tonlgues extending within thegrooves of the m1 s.

In testimony whereof.I have signed my name to this specification in thepresenceof two subscribing witnesses.
